The encryption service in the application currently uses a weak cryptographic mode, which may expose sensitive data to potential security threats. Weak modes (e.g., ECB mode for AES) do not provide sufficient protection against certain types of attacks, making it easier for attackers to infer patterns in the encrypted data.
Impact
Using a weak cryptographic mode can allow unauthorized entities to:
Decrypt sensitive information if partial plaintext information is known.
Perform cryptographic attacks that reveal patterns, which can lead to data leakage.
Compromise data integrity by tampering with encrypted content without detection.
Recommended Solution
Update Encryption Algorithm: Replace the weak cryptographic mode (e.g., ECB) with a stronger mode such as CBC or GCM for AES encryption. GCM is generally preferred for authenticated encryption.
Use a Secure Initialization Vector (IV): Ensure that each encryption operation uses a unique and unpredictable IV to prevent replay and pattern detection attacks.
Implement Key Rotation: Regularly rotate encryption keys and implement a secure process for key storage and management.
Run Security Tests: After implementing changes, conduct penetration testing or cryptographic analysis to verify the security of the encryption implementation.
